Re: Unable to start regionserver in distributed mode
also make sure that you have proper name resolution as it is vital for a
healthy Hbase operation. Sometimes even after configuring everything
perfectly Hbase refuses to work as intended just because of improper name
resolution. Add the actual host name along with their IPs in the /etc/hosts
file.

Warm Regards,
